What to tell the machine shop

So, I am starting to gather a few things, I am considering two different intake manifolds, the Clifford and the Aussiespeed. I like the Clifford because it has the pre heater built in. But, a pre heater can be added to the Aussiespeed manifold. So, which one do you like better and why?
